1. General information
Dear customer,
By purchasing a GEIGER rain sensor you have decided on a quality product from
GEIGER.
Thank you very much for your decision and the condence placed in us.
2. Guarantee
In the case of incorrect installation contrary to the operating instructions and/or constructional
modication, the legal and contractual guarantee for property damage and product liability
lapses.
3. Sensor-specic safety information
Please observe following instructions in order to avoid damage to this product:
fThe device is only suitable for low voltage and should not be operated on mains
supply.
fThe relay contact is only suitable for low value signals and should not come in
contact with mains supply.
fThe protection type is only given with an intact casing, the cover screws and the
cable gland must be properly tightened. The cover gasket inside the sensor cover
must be intact.
fThe suitability for certain applications should be checked by the user.
4. Mounting
The installation of the rain sensor must be carried out by an authorized electrician. The relevant
safety regulations must be observed. The rain sensor can be mounted on a wall/mast holder.
Otherwise, make sure you have a horizontal mounting bracket approx. 30 °. The tips of the
sensor surface must point downwards. The rain sensor should be installed at some unprotected
place where the rain falls down. Dripping water can delay the switching back or lead to a
permanent ON/OFF operation.
Matching mounting accessories (article nr.GRS002) must be ordered separately.

5. Connection
After unscrewing the sensor cover, the control cable is inserted in the cable gland M16.
Supply voltage is to be connected to the terminals VCC and GND. The potential free change-
over contact is connected to the terminals NC, COM, NO.

Factory settings: S3 - S2, T1 - T2, HZ1 - HZ2
6. Signal generator output (optional)
A passive Piezo signal generator can be connected to the
connection terminals (pin BUZ and GND). The condition of
the signal (acoustic signal for dry or wet) can be selected
with the jumpers S1-S2 or S2-S3. In the default setting
S2-S3 the signal generator is inactive in case of rain.
7. Switching behaviour
The switching behaviour of the relay (energized or
de-energized in case of rain) can be selected by moving
the jumpers between T1-T2 or T2-T3. In the factory setting
the jumper T1-T2 is inserted and the relay is energized
when the sensor surface gets wet.
8. Heating
The sensor surface is heated when the jumper of HZ1-HZ2 is inserted. The heater should be
switched on to ensure faster drying or to enable operation at temperatures below freezing point.
In order to detect fog, the heater can be switched off.
9. Sensitivity setting
The sensitivity of the rain sensor can be adjusted via potentiometer. A higher sensitivity is
achieved by turning the potentiometer clockwise (left = high sensitivity, right = low sensitivity).
The middle position is most suitable for a normal rain signal.
Please note that no functions are affected to the end stops.
